Abstract
A full complement antifriction bearing includes an inner race, an outer race, and rolling elements organized in a circular row between the races without a cage or retainer for separating the rolling elements. While the absence of a cage or retainers enable the bearing to have the maximum number of rolling elements and thus transfer greater loads, adjacent rolling elements contact each other. Each rolling element or every other rolling element is covered with a tribological coating that retards adhesive wear and reduces friction.
